Automotive relays have been around for decades, playing a crucial role in car electrical and safety systems. Relays are used to control the voltage and current flow to electric circuits, making them ideal for controlling complex functions such as headlamps, fog lamps and cooling fan. The CB1-R-SM-12V relay is one of the most popular automotive relays used in various applications in the automotive industry.

One of the common application fields for the CB1-R-SM-12V relay is in the auto starting system. The system uses the relay to send power to the starter motor when it receives an electrical signal from the ignition switch. The relay is connected to the starter motor and the relays contacts open and close to control the flow of current from the battery to the motor. This allows the starter motor to crank the engine and start the car.

The CB1-R-SM-12V relay is also used in automotive lighting systems such as headlights and fog lights. The relay is used to send power to the lights when the switch is turned on. The relay contacts open and close when the switch is activated to allow the power from the battery to flow to the lights. This is important to ensure that the lights turn on and off to allow the driver to see in darkness.

The CB1-R-SM-12V relay is also used in automotive cooling systems. It is used to control the flow of power to the cooling fan, allowing the fan to turn on and off as necessary to keep the engine from overheating. The relay is wired to the cooling fan and when the temperature rises, the relay contacts open to allow the power from the battery to flow to the cooling fan. This helps keep the engine at optimal operating temperatures.

The working principle of the CB1-R-SM-12V relay is a simple one and relies on the use of a coil to control the flow of current. When power is applied to the coil, a magnetic field is created that causes the switch contacts to close. This allows the power to flow through the relay switch and to the circuit controlling the fan, lights, or starter motor. When the power is removed, the magnetic field collapses and the switch contacts open, cutting the power to the circuit.

In summary, the CB1-R-SM-12V relay is a popular type of automotive relay used in various applications. It is often used in auto starting systems to send power to the starter motor and in lighting and cooling systems to control the flow of power. The relay works on the principle of using a magnetic field to close the switch contacts, allowing power to flow and cutting power when the field collapses.
